We introduce a Multi-modal Neural Machine Translation model in which a
doubly-attentive decoder naturally incorporates spatial visual features
obtained using pre-trained convolutional neural networks, bridging the gap
between image description and translation. Our decoder learns to attend to
source-language words and parts of an image independently by means of two
separate attention mechanisms as it generates words in the target language. We
find that our model can efficiently exploit not just back-translated in-domain
multi-modal data but also large general-domain text-only MT corpora. We also
report state-of-the-art results on the Multi30k data set.

我们引入了一种多模态神经机器翻译模型，其中双重注意力解码器自然地整合了使用预先训练的卷积神经网络获取的空间视觉特征，弥合了图像描述和翻译之间的差距。我们的解码器通过两个独立的注意机制在生成目标语言单词时独立地关注源语言单词和图像的部分。我们发现我们的模型不仅可以高效地利用反向翻译的域内 多模态数据，还可以利用大规模的通用领域文本翻译语料库。我们还在 Multi30k 数据集上报告了最先进的结果。
